Re: [PATCH] net-proc: expose the tos values in /proc/net/[tcp|udp]

[MuraliRaja Muniraju]

I shall make the changes by exposing the tos values via the
netlink as suggested. I had a doubt is I have to modify the
inet_diag_sockid or export it via a new option. I am considering
that adding into inet_diag_sockid is better because the latter is a
bit of a over kill for a single value to be exposed and it also seems
to be logical fit.
Can you let me know your thoughts on this.

Thanks,
Murali
